Prevent crash on division by zero Currently, attempting to divide by zero in an integer expression in a dts file will cause dtc to crash with a division by zero (SIGFPE). This patch corrects this to properly detect this case and raise an error. Reported-by: Anton Blanchard <anton@samba.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

Prevent crash on modulo by zero 1937095 "Prevent crash on division by zero" fixed a crash when attempting a division by zero using the / operator in a dts. However, it missed the precisely equivalent crash with the % (modulus) operator. This patch fixes the oversight.
